Outcross Bulls & BDGP

Outcross Bulls & BDGP

Overview Q: What is an outcross bull? Ans: A bull with a bloodline that has never been used here before. My Technical Definition: The AI bull s Sire, Sire s Sire and Dam s sire do not have AI Codes and were not widely used by Pedigree Breeders in the last few years They would also not be in the immediate backpedigrees (Sire. Grandsire line) of many breeding females today.

Simmental Breed Case Study 52 Sires recommended for use by their Pedigree Breeders How many have 0,1,2 or 3 popular Simmental AI Sires in their immediate backpedigree (Sire & both Grandsires)? What are the uro-stars of those outcross bulls? What are their chances of improving their uro-stars?

Proportion of Outcross Bulls 14 of the 52 have complete Outcross pedigrees

Reliability % of outcross bulls is generally always lower than their comrades with Popular backpedigrees. Until Rel % rises the potential benefits of using the outcross bull is unknown. 2 Factors affecting the uro-stars of an Outcross bull: Foreign data being included in his Irish figures How his semen is priced, marketed & used here. Is his semen available for use in commercial & pedigree herds? Is his semen only available on a pre-order basis to pedigree breeders? Regardless of BDGP scheme this is always an issue for such bulls.

April 2013 Outcross Bull in Widespread AI Inclusion of Foreign data in his uro-stars 8/straw in Tech Service Widely available to Commercial farmers Total Ped Calving Linear Carcass Weights Calves Calves Surveys Scores Recs 493 89 284 14 87 2

April 2015 85% His AI Usage has put enough progeny on the ground to allow his uro-stars to find their correct level in time.

April 2014 Outcross Bull not in Widespread AI Inclusion of Foreign data in his uro-stars 30/straw pre-order Widely available to Commercial farmers Total Ped Calving Linear Carcass Weights Calves Calves Surveys Scores Recs 9 7 3 2 5 -

April 2015 19% His AI Usage has not put enough progeny on the ground to allow his uro-stars to find their correct level in time.

Targeting Farmers to use semen is another approach. AHC 250 straws sent out HHJ 290 straws sent out EMS 300 straws sent out LM2014 8000 catalogues sent out. 100 s of calls made 190 straws sent out

Regardless of whether a bull is an outcross or not: Getting a large number of progeny born across a large number of herds is critical for an accurate picture of his evaluations. Some Well Proven bulls from foreign breeding programs have been used here and disappointed when their progeny arrived. Other such Foreign bulls though have delivered on their foreign figures.

2002 ULE Maternally proven bull from French Program

2015 Delivered on milk but not fertility

2008 SGO Imported from pedigree breeder in France

2015 Delivered on carcass but not on calving or maternal

2013 OZS Proven Maternal bull from France

2015 Delivering on maternal promise.

2006 PNY Proven Maternal bull from France

2015 Delivering on maternal traits.

Conclusion Factors affecting the establishment & movement of a Bull s uro-stars: 1. Inclusion of a Bull s foreign data Availability of the data & Suitability of that data for inclusion i.e. is the bull in a breeding program in the foreign country. 2. Semen Usage Prospects of the bull: Availability of his semen Is he in an AI Technician network service or pre-order? Is he in a structured program where farmers are being called? Price of his semen Is he @ 10/straw for commercial usage? Is there a royalty fee on top of the straw price?
